So I am surfing again on my Linksys WRT610N V1 which was totally bricked just a minute ago. To be honest, i was stupid enough to just flash a dd-wrt image without having read all the warnings. I decided to write a short post on how i did it, this is my first tutorial ever, but i just wanted to share this knowledge, so don't be to hard on me.

The Solution
So here comes my solution: We need a smaller image which we can flash on our WRT610N as to get a webbase possibility to flash a bigger image (I only have a V1 to test, but i guess it's the same with the V2). DD-WRT just released new images (THX to EKO).

2. We flash this image using tftp. The bin-file is small enough and its transfered successfully. There are enough guides howto unbrick Linksys Routers using tftp.

3. Do a factory reset (30-30-30). After the reboot, the power-led is still blinking,

4. Plugin a lan cable and connect to your pc, you don't get an ip. So that means the lan ports are not working and together with the light it might seem like nothing is working. (I guess when you are using V2 it works directly, so skip to step 6)

5. Now the real funny thing: Remove the lan cable and reboot (unplug) the WRT610N. Wait some minutes until the wlan light on the WRT610N goes on. Then look for a WLAN called "dd-wrt". Its unsecured, connect to it. Its working and you get an IP!!!

6. Use a Browser and go to 192.168.1.1

7. You are on your WRT610N on a running DD-WRT (only WLAN no LAN-ports! on V1)

8. After entering your new password browse to "Administration=>Firmware Upgrade"

9. I know, it's written everywhere to never upgrade new firmware usin wlan, but you want brick your WRT610N anymore then it already is. So just go ahead and choose "Reset after Upgrade" upload the file you wish (didn't work with firefox 3.5!!!):

There are a lot of posts which tell that this management system doesn't work in all cases. I was never able to see this page with the guide in the link you posted.

It does if you do it correct, most who fail has ignored removing all ethernet cables from the ports.
I don't think I have seen anyone else here in the forum saying that it doesn't work, lots of users here have succeeded doing it this way.

There are also older, small dd-wrt builds, available which you can tftp._________________I started out with nothing, and I've still got most of it left

I've tried every non-evasive fix known to man, and it is still bricked, have not tried the jtag, not so sure how that works and does not want to open the case. Can someone please help? Will try jtag if all else fails. Maybe consider sending it in to a repair shop.

There is currently no jtag support for the WRT610N.
Edit: no jtag support for WRT610Nv2

If you can't access the management page then you may have a severe brick, ethernet switch IC may be dead or the flash is totally wiped so there is no bootloader in it anymore.

It is quite easy to test:

1. Set your computer to a static IP of 192.168.1.10, netmask 255.255.255.0, gateway 192.168.1.1
Use a Linux rig or WinXP if possible, both Win Vista and Win7 has a habit of getting extremely upset if they can't find an internet connection and they will start to repair the connection and sometimes switch between home and office network settings.

Connect LAN cable between your computer and the routers LAN port, turn off wifi card in computer if any.

2. Open a cmd window and type ping -t 192.168.1.1
Turn off router.

3. Turn on router and watch your ping window for reply with TTL = 100.
If you get a reply then the switch IC and the bootloader is ok, there is a chance for rescue.

If you don't get a valid ping response then you have a severe brick._________________I started out with nothing, and I've still got most of it left

Your help worked like a freakin' charm, thanks a lot. I was just about to box it up and throw in the towel. I had to try your steps several times until I realized I needed to follow them word for word, after that, I reinstalled the Linksys firmware and it started working. Again thanks a lot.
